BLANK-REVERSING MECHANISM'FOR GLASS-HOLDS.

Specification of Letters Patent.

Patented Dec. 3, 1912'.

Application filed January 31, 1912. Serial No. 674. 35.

L aZl whom it may concern:

Be 1t known that I, VVILLIAM Hn'nnr, a

' citizen of theUnited States of America, and

' mechanism resident of 'VVellsburg, county of Brooke, and State of West Virginia, have invented certain new and useful Improvements. in Blank-Reversing Mechanism for Glass- Molds, of which the following is a specification. I

This invention relates broadly to glass machines, and specifically to blank reversing for bottle molds and the like. The primary object of the invention is to provide a press moldhaving means associ ated therewith whereby, when the-mold is opened, the .blank. formed therein is automatically reversed and carried to its proper position in an underlying blow mold.

A-further object is to provide a transfer ring and means for handling the same whereby the transfer of a glass blank from. a press mold to a blow mold and the return of the ring to its initial position is auto- -matically accomplished, resulting in the practical elimination of the labor involved in manually effecting such transfer and in a material increase in the production.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be exemplified, reference being had to the ac forming a part of this-specification, in which- Figure 1 is a side elevation of the invention, the rotary table carrying the blow molds being shown in section; Fig. 2 is a horizontal section on the line 2-2, Fig. 1;-

Fig. 3 is a'vertical section on the line 3--3, Fig. 1, showing the press mold closed in blank forming position and the blow mold open; Fig. 4: is a'similar section showing the press mold open and the blow mold closed with'the'blank reversed. and received therein; and Fig. 5 is an enlarged vertical section of the plunger mechanism.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views --1 indicates generally a two'part press mold of a common hinged type having suitable means of I support, as a supporting arm or bracket 2 is rotatable about said post or pedestal and carried by a post or pedestal 3. A table 4 has mounted thereon blow molds .5 of an ordinary two part hinged type adapted to be successively moved into a position under lying said press mold, as shown.

Since the illustration of a single blow mold will suffice in arriving at a clear understanding of the present invention, but one is herein shown.

Pivotally mounted upon the bracket-like end 6- of a rotary horizontal shaft 7 is a transfer ring 8 comprising two hinged sections 8 and 8 having complemental bottle-' neck-formingrecesses 9 therein and adapted for having a plunger 10 operate cent-rally t'herethrough. One of the sections, as 8, has formed integral therewith on its face .an

extendedboss-like lip 11 which is provided wlth a central aperture alining with the plunger passage in the body of. thej ring. Fixed at diametrically opposite points in the face of said lip are the ends of two parallelv vertical posts 14 which serve as guides for a flanged collar 15 fixed upon the outer end of a plunger 10 which has its opposite end slidably supported in said central aperture. A coil spring 16 encircles the plunger, having one end seated against the collar 15 and the other against a suitable fixed bearing surface whereby said plunger is. normally maintained in a retracted position with .respect to a blank 17 formed in the press mold. An anti-friction roller 18 suitably mounted at the outer end of the plunger is adapted to be engaged by suitable plunger operatin means, as by a lever 19, when it isdesire to elevate the same for forming an ail-pocket in the blank, as shown in Fig. 3. A suitably operated compress plunger 20 is preferably clearly shown in Fig. 3.

Fixed on the Shaft 7, which is rotatable in appropriate bearings 21 and 22, is a gear wheel 23; and fixed to one of the movable sections of the press mold is a horizontally disposed arm, of bracket 24: which carries upon; end an arcuate rack segment 25 which engagement with said gear wheel when saidsectlon 1s swung outward in opening the mold. As is obvious, outward swinging movement of said mold section, beyond the point where the rack-bar or segment 25 first for compressing the molten pted to be'movedinto operative engages the gear wheel, acts to rotate the shaft 7 upon which said wheel is mounted and, consequently, to "swing laterally the transfer ring S, the plunger mechanism carriediby said'ring, and the blank 17. formed inf-said moldand supported by said ring,

the purpose being to reverse the blank to an upright position-within the blow mold lo-- cated directly beneath said press-mold, itbeing of course understood that said blowmold is in open position, as shown in Figs. 1

' and 3, for the reception of the blank.

In order to provide for the free and unobstructed lateral movement of the transferring and -the,blank to reverse position, as above indicated, the press-mold sections must be opened sufficiently to clear said ring before rotationbegins; hence the rack-seg-' ment is so positionedon the one section of the mold that it does not engage the gear wheel until said clearance has. been efiected.

When the blank has been reversed, as describemthe blow mold 1s closed, as shownin. e, and the blowing operation is performed in theusual manner, air being admitted from a suitable source through a flexible connect'ion, as a hose 26, to and through a passage 27 provided in'the plunger 10. At the conclusion of the'blowing operation, both the blow-mold and the transfer ring are opened, whereuponthe ring and associated parts may be. automatically returned to their initial position by closing of the press mold.

The usual mouth-shaping sleeve 28, losated in threaded engagement with the transfer ring and embracing a portion of 'the'plnngenis preferably employed in the manner well known to those skilled in the art. I

From the foregoing it will be seen that I provide extremely simple and eflicient means whereby the opening and closing of p orted blank-forming mold, of a rotary shaft, a transfer ring carried by said shaft and adapted to cotiperate with said mold,

and means controlled by opening and clos-' ing movements of said mold whereby said shaft is rotated to reverse the position of said ring and to return said ring to initial position, respectively.

2. The combinatirnwith a suitably supported blank-forming mold, of a rotary member, a transfer ring carried by said member and adapted to coliperate with said mold, and means controlled by movement of the mold sections from and to closed position whereby said chamber is rotated to reverse said ringand to return the same to initial position, respectively.

3. The combination with a blank-forming mold, of a blow-mold located'beneath said blank-forming mold at a spaced distance therefrom, a rotary shaft, a transfer ring carried by said shaft, and means controlled by opening movement of said blank-formlng Y mold whereby said shaft is rotated to produce thereversal of said ring for depositing a blank in a position to be embraced by said blow mold, said means being actuated to return-said ring to initial positionby closing movement of said blank-forming mold. 4. The combination with a blank-forming mold, o-fatransfer ring associated therewith, a support for. said ring, and cooper-- ative'means carried by said mold and by said support whereby opening of the former efiects a partial rotation of the latter for reversing the position of the ring.

5. The combination with a supporting member, of a sectional blank-forming mold carried thereby, atransfer ring in cooperative relation to said mold, a rack-barcarried by one ofthe movable sections of said mold, and means'cont-rolled by movement of said rack-bar whereby partial rotation of said transfer ring is effected.

6. The combination with a supporting member, of asectional blank-forming mold carried thereby, a rotary shaft, a transfer ring carried by said'sha'ft, a gearv wheel operative'ly associated with said shaft, a rack-bar carried by one of themold sections, said rack-bar being actuated by movement of said mold section to rotate said gear wheel and shaft for reversing thev position of said transfer ring.

7. The combination with a supporting member, of a sectional blank-forming mold carried thereby, a rotary shaft, a transfer ring carried by said shaft, a gear wheel operatively associated with said shaft, an ,arcuate rack segment carried by one of the mold sections, said segment being actuated by movement of said section to rotate said gear wheel and shaft for reversing the transfer ring.
